ABSTRACT:
An actuator of the type used in interacting with optical storage media includes a lens housing coupled to a stationary member by four X cross-section flexure arms. The lens housing has coupled thereto a coil assembly which, when current flows through at least one of the component coils of the coil assembly, interacts with a magnetic structure resulting in motion of the lens housing relative to the stationary member. The lens housing, the stationary member, and the flexure arms are fabricated from two identical members. The members have structure fabricated therein which permits the accurate positioning of the identical members during assembly. The flexure members have generally orthogonal thin regions which determines the motion of the lens housing relative to the stationary member. The coil assembly includes rectangular coils which are easily fabricated and conveniently assembled.
